ILLUMlNATlNG-TILE.

v SPECIFICATION forming part of Letters Patent No. 369,196, dated August30, 1887.

Application filed May 26, 1 887.

To all whom it may concern.-

Be it known that I, JOHN W. MARK, of New York city, in the county of NewYork, and in the State of New York, have invented certainnew and usefulImprovements in Illuminating- Tiles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which- Figure 1 is aperspective view of my tile before the lenses are inserted. Fig. 2 is alike view of the same with the lenses in place. Fig. 3 is a section uponline was of Fig. 2, and Fig. 4 is a like view of the same with the tileconstructed in two parts.

Letters of like name and kind refer to like parts in each of thefigures. The objectof my invention is toso construct anilluminating-tile as to secure a maximum amount of lens area withoutimpairing the strength of the structure; and to such end said inventionconsists, principally, in an illuminatingtile which is provided withround light? openings that are each surrounded by an annular curb, whichintersects and forms part of each of the adjacent curbs, whereby thespace between the light-openings is reduced to a minimum, substantiallyas and for the purpose hereinafter specified.

It consists, further, in an illuminating-tile which is provided withround light openings that are surrounded by annular intersecting curbs,and between such curbs is provided with recesses for the reception ofcement,tiles, or glass or other like material, substantially as and forthe purpose hereinafter shown.

It consists, further, in an illuminating-tile which is composed of abase having circular light-openings and a superimposed body that isformed by annular intersecting rings, which constitute curbs for thelight-openiugs, and are each adapted to receive and contain a lens,substantially as and for the purpose hereinafter set forth.

It consists, finally, in an illuminating-tile which is provided withround light-openings that are surrounded by annular intersecting curbs,and between such curbs is provided with recesses, in combination with.leuses which are secured within said curbs and with a cement, glass,ortile filling for said recesses,

sides joined together,and at their points of intersection have only thethickness of a single curb, by which construction the space betweencontiguous light-openings a and a is reduced to a minimum, and the tileis given a maximum illuminating capacity, while the strength of thestructure is materially greater than would be possible were said curbsseparate from each other instead of being joined. Said tile and curbsare preferably cast together but for some purposes maybe formedseparately and united byscrews Band B, as shown in Fig. 4.

Within each curb a is placed a lens, 0, which rests upon the ledge c andis secured in place in the usual manner by means of cement D, that isplaced within the space between its periphery and said curb. Betweeneach four of said curbs is left a recess, a that is preferably filledwith a cement, D, plain or 'colored, but may, if desired, be filled witha fancy tile or glass bedded upon cement; but in either case suchfilling should come flush with the upper edges of the curbs, so as toconsti tute part of the walking-surface of the illumiing-tile and toafforda firm bearing for the feet.

Having thus described my invention, whatI claim is- 1. Anilluminating-tile which is provided with roundlight-openings that areeach surrounded by an annular cu rb,which intersects and forms part ofeach of the adjacent curbs, whereby the space between the light-openingsis reduced to a minimum, substantially as and for the purpose specified.
